Abstract

The rescue device consists of a trigger device in which a drum (1) with a cable (2) is arranged. The drum (1) is rotatably mounted on two sides (8, 9). A pinion (3) is arranged between the sides and is engaged with the toothing on the circumference of the drum (1). A groove of the guide pulley (4) is located in the axis of the trigger device to stabilize the vertical position of the trigger device. The braking device is formed by a pressure disk (5) in the regulator housing (6). A suspension eye (7) is provided in the lower part of the suspension device for hanging the suspension straps consisting of an intermediate strap (9) and a chest strap (10). At the point of contact of the two straps (9, 10) there is a hinged part which is provided with a carabiner (11) for hanging into the opening on the lowering device. The device is used to rescue an individual in an emergency leaving the high-rise building. The operation of the device derives from the weight of the load being lowered, ie the person being rescued. The device itself stabilizes the descent speed and allows the descent rate to slow down by the braking device.

Description

The rescue device consists of a lowering device in which a drum (1) with a cable (2) is arranged. The drum (1) is rotatably supported on two sidewalls (8, 9). A pinion (3), which engages with the toothing on the periphery of the drum (1), is arranged between the sidewalls. In the axis of the lowering device there is a groove of the guide roller (4), which stabilizes the vertical position of the lowering device. The braking device is formed by a pressure disc (5) in the regulator housing (6). In the lower part of the suspension device there is provided a lifting eye (7) for hanging the suspension straps, consisting of an intermediate strap (9) and a chest strap (10). At the point of contact of the two straps (9, 10) there is provided a suspension part, which is provided with a carabiner (11) for suspension into an opening on the lowering device. The device is used to rescue individuals in case of emergency leaving high-rise objects. The operation of the device is derived from the action of the weight of the lowered load, ie the person being rescued. The device itself stabilizes the twisting speed and allows the deceleration rate to be slowed by the braking device.

Rescue equipment for high-rise objects

Technical field

The invention relates to a personal rescue device for emergency abandonment of high-rise objects, where the use of other escape means is prevented. The rescue device can be used individually, independently of the assistance. The rescue device is easy to carry with regard to its light weight and small size.

BACKGROUND OF THE INVENTION

Currently, many ways of rescuing endangered people trapped in high-rise buildings are used, where it is prevented from leaving the building with standard equipment. High-rise buildings can be residential buildings, high-rise buildings, rock formations, ocean liners, airliners on the ground, etc.

The way of rescuing endangered persons is given by the current situation and the possibility of using available technical means, which are available for the given place and situation. For this purpose, there are ladders, slides, rescue sails, helicopters, parachutes, outdoor emergency staircases, etc. For example, a safe rescue height without lighting can be considered to be below 2.5 m without serious injury.

However, the aforementioned life-saving equipment does not have the character of a personal life-saving equipment and is mostly tied to the help of the persons called in. Transported rescue equipment to the rescue site has limited usability whether it is height, low rescue capacity, preparation of rescue equipment for the action, a certain number of trained rescuers. Some life-saving equipment is very expensive and last but not least it should be taken into account that all equipment must be transported from somewhere to the place of rescue. The speed of the rescue operation must be at the earliest possible time before panic and stress are at risk.

SUMMARY OF THE INVENTION

Personal rescue equipment for emergency exit from high-rise objects solves many disadvantages of currently used rescue means. The way of rescue is focused on the own initiative of the endangered individual in a catastrophic event. Said rescue device enables to leave the height object by means of a lowering device on the rescue area. The rescue operation carried out by this facility is not dependent on the assistance of other persons. The device is usable in seconds from • · · · · a

-2decided decision. The essence of the invention is that the rescued person is lowered to a safe rescue area by means of a rescue device at a suitable constant speed.

The rescue device consists of two main parts of the fastening straps and the lowering mechanism. The protruding end of the cable from the trigger mechanism is clamped by a loop to a solid object in the room, on the roof or the like. and the other end is fastened with a carabiner to the straps. The rescue device is equipped with a descent control. The braking device can brake the speed from a constant descent to a stop. The start speed is controlled by a centrifugal regulator. Clamping straps are equipped with a quick release lock. This device is easy to handle and can be used in various fields as well as for various high-risk workplaces and also in mountaineering.

The rescue device can be used in the operational height from 2 up to more than 200 m (depending on the height of the operating object, the length of the trigger cable is used. The rescue device can be used multiple times, depending on the wear condition). environment.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The invention is illustrated in the drawing, in which a rescue device kit consisting of two basic parts is shown. parts A and part B.

Thus, Fig. 1 shows a complete assembly of the lowering device, which consists of a mechanical part A and a textile strap fastener.

Exemplary embodiment

Fig. 1 shows the principle and description of the operation of the triggering device, which consists of a drum with toothing on the circumference in which the trigger cable 2 is wound. The drum is rotatably mounted in two sidewalls 8, 9. in engagement with the teeth on the periphery of the drum. The pinion transmits the torque to the centrifugal regulator, which is formed by a bushing in which the arm with a set of brake weights is located, which stabilizes the unwinding speed of the suspension cable. A groove of the guide roller 4 is located in the axis of the triggering device, which stabilizes the vertical position of the triggering device. The braking device is formed by a thrust disc 5 in the housing of the regulator 6, which during braking is controlled by the thumb of the left or right hand (or both) with the buttons.

• • • • • • • • • • • • • • • • • • • • • • In the lower part of the suspension device, a suspension eye 17 is provided for suspending the suspension straps.

Part B is a suspension strap for the rescued person, it consists of two parts, namely the 9th interstage strap and the 10 chest strap (armpit). The length of the straps is adjustable according to the size of the rescued person. At the point of contact of both straps there is a suspension part provided. a carabiner 11 for hanging into an opening on the trigger device A.

The procedure for rescuing an endangered person is as follows. a protruding cable 12 from the unwinding drum is fixed by an end carabiner to a fixed object. the hitched device grips the rescued person with both hands at the anchorage points, depresses the braking mechanism and releases the braking mechanism after leaving the danger area. The rescue device even with the rescued person goes into a constant descent, which can be slowed by the occupant-triggered braking.

An example of the use of the rescue device is shown in Fig. 2.
